Food items quality and quantity were used as a valuable tool to assess the environmental quality. The study was based on samples collected from 1995 to 1998, besides published data since 1979. Groups interactions were based on food items of 27 fish species. The Sorensen similarity index was used for cluster analysis. Many different taxa
